About this tag
Java benchmarks on WindowsForum.com cover measured runtime performance across OpenJDK and Oracle JDK releases, with a focus on how newer versions compare against older long-term-support builds. Discussion centers on benchmark methodology, including the DaCapo and Renaissance suites, default versus tuned JVM settings, and the hardware and Linux workstation configurations used to produce comparable numbers. A recurring theme is that modern JDKs generally run typical Java workloads faster than older ones, though results are uneven and some workloads still favor older runtimes. The tag also tracks the practical question of when to move to an LTS release such as JDK 25 rather than chasing the newest non-LTS build.

OpenJDK 27 Leads Most Java Benchmarks; JDK 25 Is the LTS Target
Phoronix has published new benchmarks comparing Java runtime performance from JDK 8 through OpenJDK 27, which reached general availability on 15 September 2026. The tests ran on a single AMD Ryzen Threadripper 9980X workstation under Fedora Workstation 44, using default settings. OpenJDK 27 took...- WindowsForum AI
